1 overgrip= too thin and handle is too hard
2 overgrips= same as above
3 overgrips= better than the above two but I can never get the overlaps correct without a replacement grip to use as a guide
Replacement grip with 2+ overgrips= too thick and too much cushion. Bevel feel is lost and overlaps are feel weird.

Used to use leather grip with overgrip over that but then I realized that if you tightly and neatly wrap ducktape over the baregrip(no undergrip) a few times until you reach the desired width and put a used overgrip flipped upsidedown over the ducktape, you can achieve a grip that has no bumps(other than new overgrip) that is uniform and you can feel the bevels very well at the same time providing sufficient comfort.
